Installing CPANEL on your VPS or Dedicated Server

Make sure that your VPS server has enough resources to be able to run Cpanel. Minimum of 512 MB of memory to run Cpanel (1GB is recommended).

Before installing Cpanel, its good to setup a basic clean compile environment and get your server up to date with the latest patches and software updates.


# yum install selinux coreutils binutils make dialog gcc gcc-* glib*
# yum install libexi* libjpe* libpng* gifl* freetype curl curl-* xmlrpc
# yum upgrade kernel*
# yum update

Once you got the basics, time to install Cpanel/WHM:

# cd
# wget http://layer1.cpanel.net/cpanel-universal-install.sea
# chmod 700 ./cpanel-universal-install.sea

Test your installation by checking this URL;
